#00135D

General Information

Gulf Blue, represented by the hexadecimal color code #00135D, is a deep, rich shade of blue. It belongs to the blue color family and has a significant presence of blue pigment with very little red or green. In the RGB color model, it consists of 0% red, 7.5% green, and 36.5% blue. This creates a color that is perceived as calming, sophisticated, and somewhat mysterious. The name Gulf Blue evokes images of the deep ocean, conveying a sense of depth and stability. In color psychology, dark blues like Gulf Blue are often associated with trust, intelligence, and authority. It is a color that is less commonly found in nature compared to lighter blues, which adds to its unique and refined appeal.

The hex color #00135D, also known as Gulf Blue, presents significant accessibility challenges, especially when used as text on a white or light-colored background. Its low lightness value results in very poor contrast, making it difficult for individuals with visual impairments to read or distinguish elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Gulf Blue falls far short of these recommendations. To improve accessibility, consider using a much lighter color for the text, such as white (#FFFFFF) or a pale yellow, or using Gulf Blue sparingly for decorative elements where legibility is not critical. Providing sufficient contrast ensures that content is usable by everyone, including those with low vision or color blindness. Avoid using it for important links or buttons without adequate visual cues.
